• 1x BNC antenna port
The BST30/35 base station supports up to two voice groups, relaying through to the intercom
on two separate intercom interfaces. One of the interfaces can support a PTT line supplied
from the BST30/35 to the intercom. The PTT line can be driven by the BST30/35 triggered by
wireless communication, or it can be set up to replicate PTT keying from the handsets
(remote PTT keying).
The BST30/35 can relay position data from an GPS enabled PNG handset. The position data
can be supplied from the base station to a mission system as NMEA data, allowing tracking
of the wireless crew in moving maps, and target locking for search light and similar.
Integration between moving maps and PNG system is supported by major map system
suppliers, among others Euronav, Churchill, and Aerocomputer.
When the BST30/35 is connected to a wired intercom system, the lost intercom port can be
replicated through the BST30/35 headset port, supporting both high and low impedance
systems.
When installed in an aircraft or vehicle the antenna port can be connected to an external
antenna for optimal range and coverage.
NOTE: The antenna port shall always be terminated when the base station is powered.
Failure to terminate the antenna port may destroy the output amplifier.
1.3 Portable install
The BST30/35 is intended for a temporary/portable install and as such regarded as carry
on/ground support equipment.
The BST30 requires external power supply through nominal 28VDC, while the BST35 can be
supplied external power or operated from internal batteries allowing up to 10 hours operation.
Both versions can be equipped with a BNC antenna (different versions available from Axnes)
or connected to an external antenna mounted on the aircraft/vehicle/vessel.
The base station can be operated connected to the platform’s intercom, or it can be operated
stand alone. The Base station headset port can be operated independent of connection to
wired intercom.
The base station can be installed in a bag, or in a pouch available from Axnes. Axnes will
also have mounting brackets available.
1.4 Charging
The BST35 has integral batteries allowing up to 10 hours of continues operation. The
charging of the batteries is possible through the USB type C port, and a USB type C power
supply of minimum 45W are required (available from Axnes). The equipment can be
operated while charging. It is also possible to charge batteries from the external 28VDC
power. This option is configurable as some platforms typically will have restrictions for
charging in some operational modes.
